Well, I've heard that it DOES cause more long from an actual powertrain engineer with Stellantis who designed the gen 1 of the 3.6 in most Gladiiators. He won't run it in his own flex fuel 3.6. I'd think he's in the know about it. I also know a racing engine builder who will tell you exactly the same thing, and many of his engines run on E85 and some on pure alcohol fuel. He obviously isn't concerned about long term wear, but understands what it does in an engine compared to gasoline.That E85 bit is myth anyway. I
t doesn't damage engines. State vehicles are mandated to run it and those cars go as long as any other engine would. It doesn't wash off oil. For one thing, it shouldn't be so wet in the combustion chamber that it could wash anything if it would.
Too many myths from those haters who haven't used ethanol like I have.
Besides, 4 cycle engines have two times per cycle where the piston is up at the top - TDC, and the rings and piston carry oil up the cylinder wall, and the rings themselves are "Scrapers" and scrap oil off the cylinder walls as the piston goes back down.
The alcohol is also so hot when it gets into that compressed mix it's not liquid - there's no liquid to wash oil off the cylinder walls. I see a lot of people out there claiming it while real life studies show otherwise. Another hate myth.
A study from Finland years ago showed equal wear ethanol fuels vs. straight gas.
We had state cars with 100,000 miles on them and no engine trouble.
